## Summary description

Makita D-44432 is a 14 mm diamond core drill bit designed for drilling hard surfaces such as granite, marble and tile. Intended for use with compatible rotary or core drilling tools, it provides precise holes in stone and ceramic materials. Suitable for wet drilling applications and professional repair, tiling and countertop installation tasks.

## Long description

Makita D-44432 diamond core 14 mm is a specialist drill bit designed to create precise holes in hard surfaces such as granite, marble and ceramic tile. The tool is intended for use with compatible rotary or core drilling tools and is suitable for wet drilling to reduce heat and extend diamond segment life. Its 14 mm diameter makes it appropriate for common anchor and pipe pass-through applications during tiling, countertop installation and stone repair.
Advantages
The diamond cutting edge offers fast, consistent cutting performance on natural and engineered stone while minimising chipping when used with correct feed and cooling. The 14 mm core diameter provides a neat, accurate hole size with stable centring for repeatable results. Designed for wet drilling, the bit benefits from reduced friction and longer segment life when supplied with adequate water flow. The construction supports use on dense materials such as granite and marble as well as ceramic tiles.
Suitable for
Drilling holes in granite and marble for anchors, fittings and fasteners
Cutting precise pass-throughs in ceramic and porcelain tiles
Wet core drilling in kitchen and bathroom countertop installations
Professional stone repair and renovation jobs requiring clean edges
When it may not be suitable
This drill bit is not intended for general wood, soft plastics or metal drilling; using it on inappropriate materials can damage the diamond segments and reduce lifetime. It is optimised for wet drilling and may wear quickly if used dry or without adequate cooling; dry use is not recommended.
Key specifications
Diameter: 14 mm
Cutting type: diamond core
Intended materials: granite, marble, ceramic tile
Recommended drilling method: wet drilling
Suitable for use with rotary and core drilling tools configured for diamond bits
How to use
Mount the Makita D-44432 diamond core bit into a compatible holder or spindle on the drilling tool, ensuring a secure connection. Position the bit on the marked drilling point and start at low speed to establish a centration point. Apply steady, moderate pressure and maintain continuous water flow to keep the cutting edge cool and to remove slurry. Increase speed as appropriate for the tool and material, avoid excessive force or side loading, and periodically withdraw the bit to flush out debris. After drilling, clean the bit and store it dry.
What to consider before purchase
Confirm compatibility with your drill’s arbor or thread and the tool’s RPM range
Plan for wet drilling and ensure access to an adequate water supply or wet-drill adaptor
Verify the bit diameter (14 mm) matches the hole size required for anchors or fittings
Consider the frequency of use; diamond core bits are wear items and performance declines with heavy use
Usage recommendations
Use the bit with continuous water cooling, moderate feed pressure and correct drilling speeds for stone and tile. For best results on granite and marble, start with a pilot run at lower speed for centring, then proceed with steady motion. Replace the bit when cutting becomes slow or produces excessive chipping.
